Caleb, 23, ditched the normal suit for a more rocker vibe to escort the Jena, 17 and the runner up, to her senior prom in Farmington Hills, Mich., earlier in the week.

“It was a joke at first. My mom was joking about it and I was like, ‘Huh, that could be fun.’ And then we ended up being the last two so I’m like, ‘Do you want to just go to prom together,’ and he’s like, ‘All right, let’s do it,’ and it happened,” Jena shared (via People) about the date.

She added about taking Caleb to the annual dance, “He’s an awesome guy. We’ve been best friends for a couple months now. To bring him to meet all my friends is pretty cool.”

Jena and Caleb will be back together on the American Idol tour in June.
